I reached this conclusion as well. IMHO the interpreter should come
with a big warning that its results are *not* to be trusted. I wasted
several hours before I realised that the interpreter simply doesn't
handle syntactic or semantic predicates *at all*.

And since the debugger works so well, I'm not sure I really see the
point of the interpreter. It's quicker to launch, but the range of
grammars it can correctly handle is so small, it's not usually worth
it.
